best answer will be marked as brainliest....​

Answer 1

Explanation:

Most of the dirt is oily in nature and oil does not dissolve in water. The molecule of soap constitutes sodium or potassium salts of long-chain carboxylic acids. In the case of soaps, the carbon chain dissolves in oil and the ionic end dissolves in water. Thus the soap molecules form structures called micelles. In micelles, one end is towards the oil droplet and the other end which is the ionic faces outside. Therefore, it forms an emulsion in water and helps in dissolving the dirt when we wash our clothes.

Soap is a kind of molecule in which both the ends have different properties.

Hydrophilic end

Hydrophobic end

The first one is the hydrophilic end which dissolves water and is attracted towards it whereas the second one is the hydrophobic end that is dissolved in hydrocarbons and is water repulsive in nature. If on the surface of the water, soap is present then the hydrophobic tail which is not soluble in water will align along the water surface.

Answer 2

Answer:

CLEANSING ACTION OF SOAP :-

• When a soap is dissolved in water, it forms a colloidal Suspension in which Soap Molecules cluster together to form Micelles.
• When a dirty cloth is immersed in a Soap Water, the Hydrophobic end of the Soap Molecule attaches to the Oil or Dirt present in it.
• The Hydrophilic end of the Soap Molecule in the Micelles however remain attached to the Water.
• When a dirty cloth is agitated the oil or grease particle gets dispersed into the Water.
• The Cloth is cleaned thoroughly by rinsing it in clean water for a number of times.
